Mexico City is subsiding at unusually fast rates, according to satellite observations reported by multiple outlets. Space.com reports that the city is sinking by as much as 14 inches (about 36 centimeters) per year, placing it among the fastest-subsiding cities worldwide. Wired adds detail from a NASA-produced mapping of the ground motion, showing that subsidence is not uniform across the metropolitan area. In some locations, the mapped ground lowering reaches about 2 centimeters per month. Together, the reports indicate that different neighborhoods experience different rates of sinking, rather than a single consistent decline. The findings rely on satellite imagery and related geospatial measurements used to track subtle vertical changes in the Earth’s surface over time. The articles present the overall magnitude of the subsidence—tens of centimeters annually in the highest areas—while emphasizing spatial variability within the city.
